RUSSELL H. BATES AND DANIEL L. BATES, OF DAYTON, OHIO.

IACE-SHAVING MACHINE.

SPECIFICATION forming part of Letters Patent No. 380,844, dated April 10, 1888.

Application filed August 16, 1887. Serial No. 247,099. (No model.)

To aZZ whom it may 0071007 74 Be it known that we, RUssELL H. Barns and DANIEL L. BATES, citizens of the United States, residing in the city of Dayton and State of Ohio, have invented certain new and useful Improvements in Ice-Shaving Machines; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawlugs, and to letters of reference marked thereon, which form a part of this specification. Our invention relates to improvements in lee-shaving machines adapted for shaving ice to be used in cooling drinks of any kind, but especially soda-water.

The nature of our invention will be described below, and pointed out in the claims.

In the drawings, Figure l is a vertical section,the turn-wheel and pawl-lever being in full lines and the tube and follower-spindle broken away. Fig. 2 is a detached view in broken section of the iceshaver and its internal stationary scraper. Fig. 3 is a plan view of the ice-box cover, the ratchet-wheel, and the follower-screw. Fig. 4IS a broken perspective of the cam-raceway on the shavershaft, the pawl-operating lever being mostly broken away.

Like letters refer to like parts.

The entire machine is made of metal, and the external parts maybe nickel-plated for appearance.

A is the feed or ice box, which may be of any suitable size to receive the block of ice, and has a zinc lining, A, extending down to the shaver. At the bottom of the feed-box is the rotary cutter B. (See Figs. 1 and 2.) At intervals on its perimeter are longitudinal slots 1), and nearly overlapping these are knives b, the back of said knives being countersunk and attached by screws, or in any desirable way, and the cutting-edge being slightly raised above the perimeter of the cutter B. The latter is threaded ate and provided with ahub, 0, also threaded, through which passes the shaft D, which is also threaded throughout a portion of its length to makea strong fastening with the cutter and its hub. The shaft is, furthermore, keyed to the hub by pin 61 to prevent the threads from loosening, and is operated by turn-wheel E.

' The box A is so cast at a as to give a bearing to the smaller end of the cutter and also to the shaft. The large end of the cutter is open, (see Fig. 2;) but this opening is largely covered by a plate, D which may be screwed to the box A. This plateha-sasocket, c,which furnishes a bearing for the outer end of the shaft D, which is turned down to fit the socket.

To collect and guide the shaved ice into the opening f in the plate, a stationary scraper, F, is attached to said plate by screws passing through. itand the tangf of the seraper. The section of Fig. 1 cuts off the outer portion of the scraper and that part of the plate to which it is attached; but the method of fastening will be understood from Fig. 2. The scraper extends in a spiral direction through the whole length of the cutter, but should not bear too snugly against its inner surface or the hub. The cutter and its hub are shown as conical frusta, or truncated cones. This shape is advantageous for directing the shavings to the exit and keeping them away from the hub.

O is an apron for guiding the shavings into a tumbler, which may be placed beneath and held in place by the guard-fingers r.

G is a drip-chamber having outlet from which a rubber tubing may lead to any desired place H is a metallic base, and I is a marble slab.

In order to press the ice on the knives b, a follower, J, is provided, and to this is attached a screw-spindle, J, which passes through a screw-collar, j. The said collar passes through the box-cover K, and the hub of the turnwheel L being fastened to the said hub by a key, j, the hub and collar being properly cut away to receive it. The hub of the turnwheel bears on the top of cover K, and also has a circular integral ratchet, Z, surrounding it. To steady the screw and prevent the follower from striking the knives, a flanged nut, m, is placed on the top of screw J, which nut, striking in its descent the top of the hub of wheel L, prevents a further lowering of the screw, and to aid in steadying the screw and to keep it from being seen a tube, M, is attached to the hub of wheel L. The cover K is hinged at and held shut by a spring-catch, K.

We desire to call attention to the U-shaped flange or rest, 00, just above one side of the follower. The purpose of this is to permit the follower, when raised far enough, to be eas- 5 ily swung back with the lid without wedging in the ice-box; and the convenience and saving of time in having the hinged lid remove and restore the follower, as shown, will be recognized. The flange x acts as a rounded fulcrum, as it were, and allows the follower to be swung back, even when two inches below the top of the lid.

In order to operate the follower in conjunction with the shaver a lever, N, is pivoted to a lug, 0, screwed on the ice-box. A pawl, P, is hinged to the upper end of the lever and engages with the ratchet Z, the lower end of said lever being properly bent to play in the camraceway R on shaft D, and just inside of wheel E. It results from this construction that as wheel E is turned to the right to operate the shaver the pawl will turn the ratchet and wheel L to the left intermittently and gradually lower the follower, as the threaded collar 2 j will lower the screw-spindle as wheel L turns.

Whenthe ice has been shaved thin, turn wheel L to the right and the screw will ascend into the tube until the follower strikeslid K. Then X release pawl P and catch K and throw back c the lid and the parts resting on it. Now inert a fresh supply of ice and put the lid and pawl to place, and the machine is ready for operation again.

It will be understood that the shavings pass from the knives b through slots 1) to the inside of the shaver, where they collect against the scraper F, and pass out through openingf, the lower side of the scraper inclining in that direction.

The machine is constructed of few parts, is durable, efficient, and easily taken apart or put together. It will operate without tube M,

but it is better to have it for the sake of ornament.

Having fully described our invention, what we claim, and desire to secure by Letters Patent, is-

1. The combination, with an ice-receptacle provided with a cover, of a rotary cutter, its shaft, a cam-raceway on said shaft, the pivoted lever actuated by said raceway, a pawl hinged to the upper end of said lever, the upper turnwheel having a ratchet engaged by said pawl, the follower having a screwthreaded spindle, and a screw-threaded collar secured in the cover through which said spindle passes, as set forth.

2. The combination, with an ice-receptacle, of the rotary cutter, the follower, its screwthreaded spindle having a stop-nut, the hinged .lid, the upper turn-wheel having a screwthreaded collar for actuating said spindle and a ratchet, the hinged pawl actuating said ratchet, the pivoted lever, a cam-raceway operating said lever, and the cutter shaft rotating said raceway, as set forth.

3. The combination, with the ice-receptacle, of the rotary cutter having the form of a hollow truncated cone provided at intervals with longitudinal slots and knives, the truncated conical hub having its larger base adjacent to the smaller base of the cutter,the spiral scraper extending into the cutter, the cutter-shaft, and its turn-wheel, as set forth.

4. In an ice-shaver, the combination, with the ice-receptacle provided with a rotary cutter, of the follower J, having the flange x, and the hinged lid connected to and adapted to remove and restore the follower, as set forth.
